AUGER.

Specification of Letters Patent.

Patented e1, 3218.

Application filed June 21, 1917. Serial No. 176,189.

To all whom it may concern:

Be it known that I, MORGAN L. GREEK, a citizen of the United States, residing at Myra, in the county of Pike and State of Kentucky, have invented certain new and useful Improvements in Angers, of which the following is a specification.

This invention has relation to angers or drilling devices, and has for an object to provide a portable device adapted to be held against the breast and including an auger and gearing manually operable to rotate the auger.

Another object of the invention is to provide a drilling device having the above named characteristics and embodying a rest of a novel construction permitting the device to be held against the breast of the operator and to provide for comfort and to relieve pressure'on the breast while the machine is being operated.

A still further object of the invention is to provide a breast drill of an extremely simple construction embodying few parts permitting th device to be economically manufactured.

In addition to the foregoing my invention comprehends improvements in the details of construction and arrangement of the parts to behereinafter more fully described and particularly set forth in the appended claim. I

In the accompanying drawings in which similar and corresponding parts are designated by the, same characters of reference throughout the several views in which they appear:

Figure 1, is a view in front elevation of an auger constructed in accordance with my invention, and

' Fig. 2, is a view thereof in edge elevation.

With reference to the drawings, 10 indicates generally the frame of my improved anger, comprising parallel side strips 11 of resilient material, connected at one end by (means of an integrally formed connecting bar 12, a second connecting bar 18 spaced inwardly from said bar 12, and a third bar 14 spaced from said bar 13 defining a space between said bars 13 and 14 in which to inclose the gearingtobe described. The opposite ends of the side strips 11 are formed with eyes 15 reacting with leaves 16 forming a hinge joint, the eyes and said leaves beingconnectcd by means of pintles l? to provide for relative movementef the leaves and the ends of said side strips. A. rest 18 is provided comprising strips 19 connected at meeting ends by means of ahinged joint 20 whereby to dispose said members 19 in alinement.v

The leaves 16 are secured to the sides of the members 19 at points adjacent the free terminals thereoef Which free terminals are curved as at 20 to engage around the sides of the body when the rest 18 is applied to the breast during operation of the device. It is to be noted that the side strips 11 between the cross bar 14 and the terminals of said strips are suiiiciently long to permit flexing of said side strips, and with 'ic this objectin view the strips should be made of some resilient material. I

A drive shaft 21 is mounted to extend transversely of the side strips 11, and is located between the cross bars 13 and 1% and journaled in the side strips as indicated. The terminals of the drive shaft are squared to receive the crank arm'22 having perforated enlargements at one end to receive the squared portions of the drive shaft, and hand grips 23 swiveled upon the arm. whereby the grips may be grasped and the drive shaft readily rotated. A bevel gear 2% is mounted upon said shaft in fixed relation thereto for meshing engagement with a second bevel gear 25 mounted upon the inner end of a driven shaft 26 which extends longitudinally of the device ormidway between the strips 11, in parallel relation thereto with one end of said driven shaft journaled in the cross bar 13, and the other end journaled in the cross bar 12. A socket 27 is formed upon the outer end of said driven shaft to receive the tang,

28 of an auger indicated at 29.

In use, the rest. portion 18 is applied to the breast of the operator and the grips of the crank arms grasped in each hand and said crank arms rotated whereupon the motion of the drive shaft will be communicated through the gears 24 and 25 to the auger to rotate. the same. This tool is designed especially for use in coal mining for drilling holes for blasting, although it will he obviousthat its uses may extend to other industries and find other applications therein.

It is to be noted that when the device is pressed against the breast of the operator,

e 'tien 1 .55 will yield being to the esisted my the strips 11 3 end which will ofier a o prevent discomfort to V e arise by the pressure reexerted neon the device when inventien W ome degree iartieular- "ity I rea ize that in vsrieus alteratiene therein er may be iii-axle I therere desire te'reserve the right and priviof the form of the details of construction er otherwise altering the artangement of the correlative parts Without 1 departing from the spirit at thein'v'ention er the scope of the appended claim.

dds-tiring thus described my Ewen vvten, What therein, such mevement tra'ted and described my messes I claim as new and desire to secure by Letally connected to one of the side members of the frame whereby the members of the breast plate are normally retained in alinement but are relatively movable, such movement being resisted by the side member of the frame. y

In testimony whereof I afl ix my signature in presence oi tWo Witnesses.
